Alvin Lee King III was an American former high school teacher and farmer, who killed five people and wounded ten others at the First Baptist Church in Daingerfield, Texas, United States on June 22, 1980.

King, who was armed with a scoped semi-automatic XM16E1-type derivative, an M1 carbine, and two revolvers, committed his rampage, after members of the church had declined his request to appear as character witnesses in a trial in which he was charged with raping his daughter. King was arrested after shooting himself and charged with five counts of murder and ten counts of attempted murder, but committed suicide in his prison cell on January 19, 1982, before he could be convicted.[1][2][3][4]
